EQUALIZING DEVICE FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 418,440, dated December31 1889.

Application filed October 2, 1888. Serial No. 286,960- (No model.)

To all whom it may concern Be it known that I, JOHN A. BRILL, a citizenof the United States, residing at Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, haveinvented certain new anduseful Improvements in Equalizing Devices for Railway-Oars, of which thefollowing is a specification.

My invention has relation to equalizing devices for railway-cars of theform which, in the event of one end of the car becoming loaded, andconsequently tending to depress it to a greater extent than the otherend of the car, are by such load at or depression of one end of the carbrought into action'to correspondingly lower the other end of the car,so as to distribute or equalize such load for keeping the car balancedand preventing inclination of the body of the car and the usual undueoscillation of said body incident thereto.

As heretofore constructed the equalizing devices or bars have beenmounted or journaled upon the car-axles; but this is objectionable, forthe reason that the friction of such bars or devices on the axles makesthe car run hard and more power is required to propel it, and isexpensive to construct and keep in repair.

My invention has for its object to avoid such described objections, or,in other words, to so support the equalizing bars or devices as not todiminish or interfere with the easy running of the car; and to this endI attach the equalizing devices to the car-axle boxes or to fixturesattached to or suspended from the axle-boxes.

My invention accordingly consists of the combinations, constructions,and arrangements of parts, as hereinafter described in thespecification, and pointed out in the claims.

Reference being bad to the accompanying drawings, Figure 1 is asectional elevation of part of a car and its running-gear, havingaxle-boxes provided with suspended springseat stirrups, and showing theequalizing devices mounted or supported upon said stirrups. Fig. 2 is alike view showing axleboxes having spring-seats and connected by bars orframing, upon which the equalizingbars are attached or supported. Fig. 3is a like view showing the spring-seat stirrups indicatedin Fig. 1provided with or having a frame secured thereto, upon which theequalizing devices are supported. Fig. 4 is a like view showing theframe for the axle-boxes in Fig. 2 dispensed with and the equalizingdevices mounted directly upon the axle-boxes; and Fig. dis a bottom viewof car, showing plan of one arrangement of equalizing devices.

A represents a car; 13 B, the wheels; 0 C, the axles therefor, and D Dthe equalizing levers or arms, which maybe constructed and have endconnection with the car-body, as desired; but I prefer to make suchconnection as hereinafter set forth. The equalizing 1e vers or arms D Dare supported or mounted upon the axle-boxes or other rigid part of therunning-gear, excepting the axles, which is not subject to its Verticalvibrations.

In Fig. 1 a form of axle-box is shown having suspended from the box a astirrup a, having spring-seats a and to these stirrups the arms orlevers D are pivoted, as indicated at d, in anysuitable manner. In Fig.3 these stirrups a are shown provided with a frame G, to which thelevers D D are attached or pivoted, as indicated at b.

In Fig. 2the axle-boxes are shown provided with spring-seats a andconnected by bars or framing G, upon which the equalizing bars or leversD D are mounted. In Fig. i said frame G is dispensed with and theequalizingbars are secured to or mounted upon the axle-boxes. I

Any form of levers or arms D D maybe used, and either they may bepivoted to the axleboxes, stirrups, or framing G, as indicated in Figs.1, 2, and 5, and have link-connections d, or these link-connections maybe pivoted to said framing, as indicated in Fig. 3, the resultantoperation in either case being the same. The ends (1 of the levers orarms D are hinged or loosely connected to fixed brackets F, secured ateach end of the car, as more plainly shown in Fig. 5.

Any of the pivotal bearings or connections for the levers D D may bearranged to have more or less lost motion to compensate for themovements of the car-body on itssprings and of the levers movingtherewith. In the drawings I have shown the same by making elongatedslots (1 in the ends d of levers D D; but said slots may be located atany of the other pivotal or bearing connections for said levers, asdesired.

The equalizing-levers D D, supported and arranged for operation asdescribed, do not impose any friction upon the axles of the car; hencethe latter runs or rides with its usual ease and no additional power isrequired to run it, and such being the case said equalizing-bars aresusceptible of use, which is not the case when they are mounted upon theaxles, as the advantage of using them then is more than offset by thenon-easy riding of the car.

In using my improvements with either the stirrups a" or with saidstirrups and frame G, as shown in Figs. 1 and 3, the yokes g for thestirrups may have a spring-support on the axle-box, as indicated at g insaid figures and as fully shown, described, and claimed in anotherpending application filed by me on the 15th day of March, 1888, SerialNo. 267,205, in order to afford a spring-supported frame for theequalizing-levers D D, and thus avoid undue vibration of same.

Instead of connecting the frame G directly to theaxle-boxes, as shown inFig. 2, it may be suspended from the boxes by means of yokes in a mannersimilar to that for the stirrups a, and as indicated in said lastnamedother application.

It will be noted that the levers D D serve as braces between the frame Gor the axleboxes and the ends of the cars, and as they do not have to befinished to fit a journal or bearing on the axle, as has heretofore beendone, they are less expensive to make and keep in repair than thosesupported upon the axles.

As it is obvious that the construction and arrangement of the details ofthe foregoing may be varied without departing from the spirit of myinvention, I do not confine myself to the same as shown and described;but

WVhat I claim is 1. In combination with a car and its running-gear, asystem of equalizing devices or arms connected to each other and attheir outer.ends to the car-body and mounted or supported upon theaxle-boxes, substantially as set forth.

2. A car having equalizing-arms D D, connected to each other and mountedor supported upon the axle-boxes, substantially as set forth.

3. In a car, the combination of frame G, supported on or suspended fromthe axleboxes, and equalizing-levers D D, attached to said frame andconnected to each other and to the car-body, substantially as set forth.

4. In a car, the combination of axle-boxes, spring-supported frame G,and equalizinglevers D D, connected to each other, supported on frame G,and connected to the carbody, substantially as set forth.

5. In a car, the combination of fixed brackets F 011 the car-body, theequalizing-levers D D, secured to each other, supported upon theaxle'boxes, and connected to brackets F, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN A. BRILL.
